Benefits of technology

The present invention provides a folding type seat that can keep excellent sitting comfort without causing any sense of incongruity when a vehicle occupant sits on the seat. The folding type seat includes a body supporting bracket and a passive section supporting bracket located inward of the external surfaces of the body supporting bracket and the passive section supporting bracket at the positions spaced by the predetermined distance therefrom. The body supporting bracket and / or the passive section supporting bracket include the impact absorbing section. This results in improved efficiency of absorbing impact energy and maintaining excellent sitting comfort.

Problems solved by technology

Accordingly, as a vehicle occupant sits on the seat, the inclined portions project toward the vehicle occupant, causing an issue of the vehicle occupant having a sense of incongruity with degradation in sitting comfort.

first embodiment

[0017]FIG. 1 is a perspective view of a seat frame forming a folding type seat of a first embodiment; FIG. 2 is a side view of the folding type seat shown in FIG. 1; FIG. 3 is a cross-sectional view taken on line X-X of FIG. 1; FIG. 4 is an enlarged side view of essential parts in an area mounted with a passive supporting bracket for supporting a passive section forming a reclining mechanism shown in FIG. 1; FIG. 5 is a cross-sectional view showing how a body supporting bracket is caused to deform rearward of a vehicle due to a load applied to the seat frame at a front of the vehicle for thereby absorbing impact energy; FIG. 6 is a cross-sectional view showing how the passive supporting bracket is caused to deform rearward of the vehicle due to the load applied to the seat frame at the front of the vehicle for thereby absorbing impact energy.

[0018]Further, FIG. 1 shows only seat cushions and seat frames with seat backs being omitted for clarifying structures of the seat frames. In F...

second embodiment

[0047]Next, a second embodiment according to the present invention will be described below with the component parts having the same structures as those of the first embodiment bear like reference numerals to omit relevant description.

[0048]FIG. 7 is a cross-sectional view, showing a vicinity of a body section supporting bracket of the second embodiment, which corresponds to FIG. 3 related to the first embodiment. FIG. 8 is a side view, showing a vicinity of a passive section supporting bracket of the second embodiment, which corresponds to FIG. 4 related to the first embodiment. Further, FIG. 9 is a side view taken on line Y-Y of FIG. 8.

[0049]With the present embodiment, the body section supporting bracket 121 and the passive section supporting bracket 122 are provided with convexed sections 131 and 141 in the form of curved sections 130 and 140, which are set to be the impact absorbing section 30.

[0050]As shown in FIG. 7, more particularly, the body section supporting bracket 121 h...

Abstract

A folding type seat of the present invention includes a body section supporting bracket, supporting a body section of a reclining mechanism, and a passive section supporting bracket, supporting a passive section of the reclining mechanism, which are located inward of external surfaces of a seat cushion or a seat back at positions spaced therefrom by predetermined distances. At least one of the brackets is provided with an impact absorbing section, which is caused to deform for absorbing impact energy imparted to a vehicle.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a folding type seat.BACKGROUND OF THE INVENTION[0002]In the related art, a seat has been adopted having a seat back provided with side portions onto which a pair of right and left side frames are provided, the side frames being provided with weakened portions, respectively (see, for instance, Japanese Patent No. 4000731). The weakened portions include inclined portions each bent in a triangular shape in cross section. When a load is imparted to the seat at a vehicle front or a vehicle rear, the inclined portions are caused to bent and deform thereby absorbing impact energy.[0003]With the seat frame described in Japanese Patent No. 4000731, however, the inclined portions are located on the side frames at front ends thereof in the vicinity of a surface of the seat back. Accordingly, as a vehicle occupant sits on the seat, the inclined portions project toward the vehicle occupant, causing an issue of the vehicle occupant havi...
